I WILL METAL AND FAN!!!!!!!!!!!!! which set of ordered pairs contains only points that are on the graph of the function y=12-3x? A. (-3 , -27) , (0 , 0 ) , (6 , 54) B. (-18 , 10) , ( -6 , 6 ) , (18 , -2) C. (-5 , 27) , (-1 , 15) , ( 8 , -12 ) D. ( -7 , -9 ) , (-4 , 0 ) , ( 2 , 18 )
HI!!
your math teacher must hate you!
hey:) lol
you have to check for each one if the second number is \[12-3x\] where \(x\) is the first number so you got a lots to do
for example, for \((-3,-27\) you have to check if \[12-3\times (-3)=-27\]
i know how to do these but i take forever on them . my test shuts off in 2 minutes so i needed someone whos fast to do it:)
Medal*
it doesn't because \[12-3\times (-3)=12+9=21\]so NO to that one
so A is incorrect?
\[12-3\times 0=0?\] NO
yeah A is a NO B is a NO
ok:)
\[54=12-3\times 6\]? not likely is it?
A fast way would be to graph the line and plot the points
so D?
i wish you could metal more than 1 person but you cant
D would make \[12-3\times (-18)=10\]
they are trying to trick you, but no it is not true
so its C
it is true that \[12-3\times 10=-18\] but that is backwards

C or D?
stop with the A, B, C, D you just gotta check each one
so far, none have worked
i have 15 sec. please need answer i will fan all of you please
ii can't do it in 15 seconds sorry
:(
you could do it really fast with the graphing method next time
you only have to check the points that are near the line
